I am working on a page and adding "Add to cart" buttons. Example:
<form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_cart"/>
<input type="hidden" name="business" value="---------"/>
<input type="hidden" name="lc" value="US"/>
<input type="hidden" name="item_name" value="xxxxxxx"/>
<input type="hidden" name="item_number" value="A11"/>
<input type="hidden" name="amount" value="35.00"/>
<input type="hidden" name="currency_code" value="GBP"/>
<input type="hidden" name="button_subtype" value="products"/>
<input type="hidden" name="no_note" value="0"/>
<input type="hidden" name="tax_rate" value="20.000"/>
<input type="hidden" name="shipping" value="5.00"/>
<input type="hidden" name="add" value="1"/>
<input type="hidden" name="bn" value="PP-ShopCartBF:btn_cart_LG.gif:NonHostedGuest"/>
<input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_cart_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!"/>
<img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1"/>
</form>
I would like to adjust it so that I have one fixed delivery charge ... rather than repeating it for each item.
